Heat pump has been subjected to the generally attention of countries in the world as a kind of power-saving technology, wherein air source and water source are most widely used, because these two kinds of heat pumps are easy to use, mounting cost is lower, produce without any pollutant during simultaneity factor work, meet very much trend and the policy of China's low energy environmental protection.But because the restriction of weather conditions, net for air-source heat pump units in China North China and the bigger clammy area of winter air humidity ratio be subjected to serious restriction.And for the zone of these water scarcities such as China East China, south China, southwest, northwest, water resource heat pump also must can not get extensive use.
Summary of the invention
The objective of the invention is to solve the problem by condition restriction such as weather, environment of above present existence, it is the novel unit of the double-source heat pump of one that a kind of Ji Kongqiyuan, water source are provided, thereby satisfies people's cooling/heating demand better.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of double-source heat pump unit comprises compressor, cross valve, magnetic valve group, condenser, throttling arrangement, evaporimeter and gas-liquid separator;
Described cross valve has four valve passages;
Described compressor, an end links to each other with first valve passage of described cross valve, the other end with link to each other with the 3rd valve passage of described cross valve by described gas-liquid separator;
Described magnetic valve group comprises four magnetic valves, is respectively first magnetic valve, second magnetic valve, the 3rd magnetic valve and the 4th magnetic valve;
Described condenser has two, and one is finned cooler, and another is shell and tube condenser;
One end of described finned cooler links to each other with second valve passage of described cross valve by described first magnetic valve, and the other end links to each other with described throttling arrangement by described second magnetic valve; One end of described shell and tube condenser also links to each other with second valve passage of described cross valve by described the 3rd magnetic valve, and the other end is by the described throttling arrangement of the same connection of described the 4th magnetic valve;
Described throttling arrangement also links to each other with the 4th valve passage of described cross valve by described evaporimeter.
Described throttling arrangement is bidirectional throttling device.
Advantage and good effect that the present invention has are:
1. adopt finned cooler and shell and tube condenser parallel connection, use finned cooler under the situation of air source (air-cooled), use shell and tube condenser under water source (water-cooled) situation, different operating modes adopt different condensers, make unit performance reach optimum efficiency.
2. throttling arrangement adopts bidirectional throttling device, namely under cooling condition from the condenser to the evaporimeter, from the evaporimeter to the condenser, all play throttling action under the heating condition.
3. this source pump all is suitable for for water source, air source, has enlarged the scope of application.Unit is more suitable for the zone of these water scarcities such as East China, south China, southwest, northwest during as net for air-source heat pump units, and is relatively low and not have the area of boiler or other heat supply conditions particularly practical to winter temperature simultaneously.Unit is during as water source heat pump units, having overcome net for air-source heat pump units can not be in the North China and the difficulty used of the bigger clammy area of winter air humidity ratio, and unit also contaminant water not of consume water not, and requires low to the water source, can be well water, river, buried water etc.
